Larry Ellison, one of the richest men in the world, will host a fundraiser for the Republican Senate fundraising arm featuring another big name — Sen. Rand Paul.

The $1,500-per-person NRSC fundraiser will be held in the former Oracle CEO's California home, according to an invitation obtained by BuzzFeed News, and will also be attended by Sen. Orrin Hatch and Rep. Steve Daines. Hosts must give $32,400 and co-hosts must contribute $15,000.

Ellison, likely best known outside his work at Oracle for his interest in sailing and yachting, has in the past been somewhat split in his political contributions. In 2012, however, he gave $3 million to Restore Our Future, a super PAC that supported Mitt Romney's bid for president.

The San Francisco-area fundraiser is part of a major campaign swing for Paul. The Kentucky senator, who is expected to run for president, is working to support Republican Senate candidates ahead of the midterm elections.
